CONCRETE SASI-I-WEIGHT.

Specification of .'.etters Patent.

Application filed March 16, 1920. Serial No. 366,348.

To all whom it may concern:

Be it known that T, ilnwam) A. Srnrrrnns, a citizen of the United States, residing at Los Angeles, in the county of Lo Angcles and State of California, have invented new and useful Improvements in Concrete Sash- Weights, of which the following is a specification. 7 p

This invention relates to building hardware and particularly to sashoveights and has for its object to provide an improved sash-weight the body of which may be made of cement to provide an inexpensive construction and a further object is to provide for the attachment'of a pulley and its bearing to the concrete blocks. -A further ob ject is to provide for the attachment of additional sections or pieces of cement bloc {S .to enable the desired counterbalance, all

with a minimum expense of time and labor and material and by the use of material of inexpensive character. sists of the construction the combination,

and in details and arrangements of the parts, embodiments of which invention are illustrated in the accompanying drawings and described and claimedhereinafter.

Figure 1 is a side elevation of a single block weight with the attached pulley.

Fig. 2 is a cross-section on line 2-2 of Fig I. Y

Fig. 3 is a plan-view of a modified form of the block having added sect-ions.

Fig. i'is a front elevation of the construction in Fig. 3. i i

Fig. 5 is a section on line 5-5 of Fig.

Fig. 6 is a section on line 66 of Fig.

The improved weight comprises a main cement block 2 of any suitable proportions and has in it upper end a pulley pocket 3 extending medially between the front and back faces of the block and transversely extending from these faces is a pair of apertures or recesses 44 in alinement with each other the parallel side walls of which form guides between which there may be disposed a transversely extending bearing part in the form of an inverted U to straddle over an inserted pulley 5 having projecting spindles 5 on each side to bear in the out turned arms 6' of the bearing member 0.

This member may be made of stamped sheet metal or otherwise and is loosely dropped into the pockets 44 in transverse position.

The bearing member 6 is secured in the The invention coninserted posi ion as by means of a fastenin wire 7 passed over the upper part of the member 6 which may be transversely grooved as at 6 to form a seat a for the fastoning wire, the ends of which are passed down over the front and back faces of the block 2. These faces are provided with grooves Sin which the wire 7 lies and the ends are bent under the bottom end of the block and twisted together as at 9 to form a secure fastening holding thebearin member in place on the spir. ile 5. Space is provided around the pulley 5 for the insertion and running of the usual sash cord C. The axial shifting of the pulley with its bearing 6 is prevented by the portions of the fastening wire 7 that engage the outer corners of the bearing parts 6 these corners being shown as turned down and arranged about in the planes of the front and back faces of the block 2.

iidditi'onal weight sections may be added at either end of the block as shown in Figs.

3 to 6 inclusive and upper end blocks of U- from turning when superposed. The top blocks 2" and 2 provide a clearance space or chamber through which the sash cord 0 may pass and the upper face of each block 2 and 2 is provided with a transverse groove 13 along which the top portion of the fastening wire 7, 5 and 6, extends when it is applied to tie the block section together. The backs of these additional sections are also grooved at 14.- to receive the wire and prevent the sections from shifting end-wise.

Bottom sections 2 and 2 may also be added to the main block 2 and the several sections interlocked by longitudinally extending interlock grooves and beads 15 and 16 respectively and the bottom block sections are also grooved in their front and back faces at 17 to receive the wire 7 From the above it will be seen that the sash-weight can be readily varied to secure the effective counterbalancing property by the addition of upper and lower sections as .may be desired and the whole can be secured by a single fastening wire such as shown at 7. V 7

Various changes may be made without departing from the spirit of my invention as claimed.

'VVhat is claimed is;

1. A sash-weight comprising, in combinationja cement block with a pulley wheel pocket in one end; a detachable bearing member adapted tobe arranged across the pocket; a pulley wheel disposed in the pocket and having running engagement with the bearing member; and a fastening device block providedat its upper end with arecess and a pocket extendlng downwardly from said recess, a detachable bearing member positioned in said pocket over said recess, a pulley journaled in said bearingand projecting downwardly into said pocket and a fastening device extending lengthwise around the cement block and over said bearpig member for securing the latter to said ilock. I

A sash-weight comprising, in combinav tion, a cement block with a pulley wheel' pocketin one end; a detachable bearing 'member adapted to be arranged across the pocket; a pulley wheel disposed in the pocket and having running engagement with thebearing member; and a fastening device for holdingthe bearing member in .place; the block consisting of interlocking sections all secured together by the same fastening means,

l. A sash weight comprising an elongated member formed of detachably connected cement blocks, one of which is provided in its upper portion with a pocl et,a bearing member arranged within said-pocket, a pulley arranged in said pocket and ournaled on said bearing member and a tie'passing lengthwise around the body of the weight for retaining the sections thereofjin assembled relation..

5. A sash weight comprising a mam .weight member with a pulley pocket in its upper end, a detachable bearing member adapted to be arranged over the pocket, said y member consisting of an inverted U-shaped guard having laterally extending portions forming half bearings, oppositely disposed recesses in theside walls of the pocket to receive the laterally extending. bearing portions, said recesses havingia depth equal to the height of the guardmember, a pulley wheel having 'trunnio'ns disposed in s the pocket, said trunnions having a bearing in r the side walls of the pocket and retained therein by the'lateral half bearingson the guard member, and fastening means extending around the main member to retain the guard and pulley in place. i

6. r sash-weight "comprising upper end, a detachable. bearing member adapted to be arranged over the pocket, said member consisting of an inverted U-shaped guard having laterally extending portions forming half bearings, opposltely disposed recesses 1n the side walls of'the pocket to receive theliaterally extending bearing portions, said recesses having a depth equal to the height'oftheguard member, a pulley a 'main. weight member with-a pulley pocket-in ltS wheel "having trunnions :disposed in the pocket, said trunnions having a bearing in the side walls of "thepocket and retained therein bythelateral half bearingslon the guard member, and fastening means extend ing aroundthe main member to retain that guard and pulley in place, and sections adapted to'be added to the main memberto increase thel weight thereof, said 7 sections having interlocking means to prevent their lateral displacement. V In testimony whereof I have signed-my name to this specification. 2 V 1 EDWARD A.
